Abstract: A process for the production of oligomerized olefins comprising the following steps: purification of an organic composition (OCI) in at least one adsorber to obtain an organic composition (OC2); oligomerization of organic composition (OC2) in the presence of a catalyst to obtain an organic composition (OC3); distillation of organic composition (OC3) in a distillation column (DI) to obtain an organic composition (OC4) from the upper part of (DI) and an organic composition (OC5) from the lower part of (DI); hydrogenation of organic composition (OC4) to obtain an organic composition (OCI 1) and regeneration of an adsorber (Al) employing organic composition (OC11) as regeneration media.

Abstract: The invention relates to a process for the regeneration of an adsorber. For the regeneration a liquid stream (S2) comprising at least one alkane is converted from liquid phase into gaseous phase. Then the adsorber is regenerated and heated by contact with gaseous stream (S2) up to 230 to 270? C. Subsequently, the adsorber is cooled first by contact with gaseous stream (S2) to a temperature of 90 to 150? C. followed by cooling with liquid stream (S2) to a temperature below 80? C. The outflow of the adsorber (S2*) during the cooling with gaseous stream (S2) and optionally the outflow of the adsorber (S2*) during cooling with liquid stream (S2) is recycled in at least one of these steps.
